State Sen. Katherine Clark (D) won the Massachusetts’ 5th special election yesterday, making her the sixth woman elected to Congress from Massachusetts. Clark was expected to easily defeat opponent attorney Frank Addivinola (R). President Obama won the 5th district with 65% of the vote in 2012. Clark will be filling Senator Ed Markey’s old seat, (D) since he was elected to the Senate in June to fill the remainder of John Kerry’s (D) term after he resigned to be Secretary of State. Clark will be up again in 2014.
